Shouldn't make a difference... Try this... shut the phone down pull the battery and pull the SIM card let it sit for about 5 minutes.... Put it back together and power it up. If that doesn't help contact your carrier about resetting the SIM card.... I used to have this issue ALL the time with my TBOLT had to go in every 2 months or so and get a new one.

With the end of the season comes countless hours of longing to be back in the woods with bow in hand and the chase in your heart.
